This system was devised by a lovely (and highly astute) gentleman - Bruce Maynard, decades ago. It is a very holistic approach that lines up better with traditional Indigenous thinking and practice. It is the miracle pill the world needs. This bloke deserves a Nobel Prize.

Given the documented trend of massively negative impacts of herbicide/insecticide use on the world's insect populations and hence entire Web of Life, it is perhaps more important than ever to adopt these methods widespread with great gusto !

Basically, No Kill Cropping allows you to have your pasture and cropping cake and eat it too. It allows 'dry' cropping into native grasslands with zero herbicide and fertilizer costs, and greatly reduced machinery costs. There is then the option of part or fully harvesting by stock to further improve soil carbon.

We absolutely can fix the joint with the right techniques, love and attention, and societal models. Please enjoy the excellent summary slides below:

Think the main obstacle to the wider use of this very Australian pragmatic technique is the belief that any plant (weed) apart from the crop plant will steal its water and nutrients. A decent academic study might help end that misconception.
Meanwhile, am surprised at the minimal response this method has received, the slideshow dates back to 2015 and there is 1 comment, a silly ad.

Yes, Weeds are just colonizer species. Any land that is growing weeds is land that needs it. They can be essential to salvaging nutrients that would otherwise 'end up in China' (a rather fun saying from my childhood of where things would end up if they fell down holes and through the earth from here and reemerged on the opposite side of the globe :) ..... leached nutrients that rely upon deep rooted vegetation to recycle them back to the topsoil to avoid desertifying soil trends.

Chemically killing weeds is madness that is destroying the land and having adverse effects on the ecosystem's and our health.

I have personally seen Peter Andrews physically demonstrate that weeds are no issue at all by pulling up random clumps of grass and weeds side by side - the grass far from being starved was actually being fed by the weed and had a healthy root system dwarfing the weeds. The weeds roots on the other hand were withered, and it had just about served it's purpose in the regeneration cycle. Note, that Peter's land actually was hydrated by NSF, regenerating and building soil by the foot, as opposed to other differently managed parts of the country in decline. Letting weeds grow is an essential part of the holistic whole.

I am not sure how the research papers are progressing in this area. I have seen enough with my own eyes (multiple earthworms curled up in the shelter of weed root systems and shade - Patterson's curse - which is no good for stock and hence mercilessly sprayed, which is a shame as from chemical free areas it makes beautiful honey). It's a non-issue .... honestly things are that dire just get on with it while the research proves you right a decade from now. There is enough extension programme and ad-hoc evidence out there already to prove it, along with the commensurate increases in soil carbon.

I have posted short YouTube demonstrations by Peter on Weeds in this thread. (I will dig up the post number later).

A lot of the kill any weed that grows brigade are just unaware of these exceedingly simple facts - instead deferring to the 'more knowlegeable' , 'scientifically advanced' big business players - unwittingly becoming a captive to the ongoing 'relationship' of the corporate model and destroying the land in the process.

Apart from this there is the very real need to have agricultural product free from contamination (other vegetative matter, non-productive seeds such as weed seeds, prior different crops etc). This is indeed a very real driver of chemical use too, apart from the perceived and real effects on crop growth of 'weed' presence. There are non-chemical means of dealing with these issues - slashing, mulching, devices such as the Harrington Weed Destructor etc.
http://www.ihsd.com/

Industrial agriculture the world over is ridiculously 'pro-chemical' and 'anti-weed'. It is big multi-billion $ business to 'own' the whole 'agriculture production system' from GM and other patented seeds to the purpose designed chemical systems involved in their production. There has been quite some M&A activity in this area (how some of it passed regulators I have no idea)
https://www.gmwatch.org/en/articles-...ho-owns-nature
https://www.investopedia.com/article...ld-syt-dow.asp

I haven't followed the investment scene in this arena but given the mounting evidence of pest/insect/herbicide use and insect decline linked to ecosystem decline, I have to wonder at the long term viability and valuations of these business models. Analogous to future investment in fossil fuels, there is just no future in it.

Thumbs up Noted US scientist says zero-till best for the environment

https://www.theland.com.au/story/665...p5w5ClBQyUsOtk

"According to US research, zero-till cropping, especially with stubble retention, results in less carbon dioxide released into the atmosphere, and supports better soil fungi bacteria ratios that are vital to soil nitrogen and carbon storage."

"These views are consistent with Australian researchers who have studied tillage and cropping systems over the last 40 years."

Thumbs up

In this time of COVID-19 , perhaps more folks are ready to start examining the link between soil health <-> food <-> nutrition <-> human health ...... perhaps even solve this climate thing ....

Not quite the entirety of what's possible with pasture cropping, but some very good points, techniques, and lessons nonetheless - particularly around building good living soil, and the web of life.

Exclamation Erosion - Dramatic 24hr Time Lapse

A time lapse video of rather dramatic erosion due to a head wall cut. In 24hrs it moves back 80m upstream in a strong flow event. That's 1000's of years of soil gone virtually overnight !

Thumbs up The Hydration Plan

An interesting wide ranging essay - with some data/maps to back up increased desertification, raised temperatures, and even bushfires etc being caused by poor land management practices.

It's a bit light on in the areas of mining impacts to surface water hydrology, river and aquifer resources, and ditto for so called 'illegal' floodplain harvesting of rain events and overland flow before even reaching our strangled and pumped dry rivers.

I'm also not pro recycled sewage water for drinking (too many unknowns).
Otherwise an interesting read.

Thumbs up Natural Processes - Rehydration by Leaky Weirs

A very nice summary animation of natural processes, damage done, and restoration. I will leave it to you to work out how much of 'climate change' this also accounts for ......
